sometimes it asks me to simplify others it does not, i never know when it will or won't accept a simlified or unsimplified version of the answer to 1/2 the time my answers are wrong. why is that?

Please help, I'm very excited to have found this program to help me study for a placement exam, i am however at a loss about the way in which i should answer the question!
